A topic map graph consists of nodes and arcs. In a well-formed topic map graph, every arc is a typed, oriented connectedness of two nodes, and every node is one of the two endpoints of zero or more arcs.
A topic map graph is composed of nodes, edges and arcs.
Even if well-formedness is retained, inappropriate here. Define each thing once and only when/where appropriate.
